Remote tissue retraction device
First Claim
1. A device for managing tissue in an organ, comprising:
- an elongated body having a proximal end and a distal end;
a tissue treatment device attached to the distal end of the elongated body, the tissue treatment device having a first jaw opposite a second jaw, the first jaw and the second jaw being movable between a closed position and an open position; and
a septum including first and second blades disposed between the first jaw and the second jaw of the tissue treatment device, the first and second blades having a sheet coupled thereto that is disposed between the first jaw and the second jaw, and the first and second blades being attached to an actuator that extends through the elongated body;
wherein proximal movement of the actuator is configured to pivot the first blade relative to the second blade such that the first blade is raised from between the first and second jaws to extend the sheet from between the first and second jaws.

Abstract
A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

10. A device for managing tissue in an organ, comprising:
-
an elongated body having a proximal end and a distal end; a tissue treatment device attached to the distal end of the elongated body, the tissue treatment device having a first jaw opposite a second jaw, the first jaw and the second jaw being movable between a closed position and an open position; and a septum having at least two blades disposed between the first jaw and the second jaw of the tissue treatment device, the at least two blades each having a first end and a second end, and the at least two blades having a sheet attached thereto; wherein the second ends of the at least two blades are attached to the tissue treatment device and the at least two blades are configured to move from a collapsed configuration in which longitudinal axes of the at least two blades are parallel to longitudinal axes of the first and second jaws, to a deployed configuration in which the first ends of the at least two blades are not directly attached to the tissue treatment device and move along an arc-shaped path. - View Dependent Claims (11, 12, 13)

14. A device for managing tissue in an organ, comprising:
-
an elongated body having a proximal end and a distal end, the elongated body being configured to extend into a patient'"'"'s body with the proximal end positioned outside of the patient'"'"'s body and the distal end positioned inside of the patient'"'"'s body; a first jaw opposite a second jaw, the first jaw and the second jaw being attached to the distal end of the elongated body, the first and second jaw being movable between a closed position and an open position; and at least one blade having a first end and a second end; wherein, when the distal end of the elongated body is positioned inside of the patient'"'"'s body and when the first and second jaws are in the open position, the at least one blade is configured to pivot, in response to actuation of an actuator at the proximal end of the elongated body, from a first position, in which the at least one blade is sandwiched between the first and second jaws, to a second position, in which the at least one blade is not sandwiched between the first and second jaws; wherein moving the at least one blade from the first position to the second position directs tissue of the patient into the first and second jaws when the first and second jaws are in the open position; wherein, in moving from the first position to the second position, the first end of the at least one blade moves distally along an arc-shaped path about the second end of the at least one blade while the first and second jaws remain stationary relative to the elongated body; further comprising a slot that receives the at least one blade after the at least one blade pivots about the second end thereof. - View Dependent Claims (15, 16, 17, 18, 19)
